Abstract (en)

[origin: US6591892B1] A method of casting a siliconized silicon carbide part. The method includes providing a pre-casting mix comprised of a silicon carbide powder having a maximum particle size within a range of about 1000 to 2000 microns, and water having a percentage by weight of no more than about 9.5% of the mix. A slurry is formed from the mix and poured into a mold. The water is then removed from the mold within a predetermined period of time to form a solid porous green part. The green part is surrounded with silicon metal, and heated to a predetermined temperature above the melting point of the silicon metal. The silicon metal then siliconizes the green part to form a siliconized silicon carbide part.
